Benefits of technology

[0005]An object of the present invention is to define a reinforcing sleeve that enhances the capacity of an automobile frame assembly to dissipate energy from an impact load imposed on the vehicle frame to avoid deformation of the frame in special locations.

Problems solved by technology

These metal reinforcement members tend to add unwanted weight to the automobile.
In other instances, the reinforcing members include complex configurations that require welding or mechanical fasteners to affix the reinforcement member to the frame.

Embodiment Construction

[0017]FIG. 2 shows a reinforced sleeve 20 formed in accordance with the teachings of this invention. The sleeve 20 includes a carrier 22 and a reinforcing medium 24 supported by the carrier 22.

[0018]The carrier 22 is an elongated member having open end portions 26, 28. At the end 26, the carrier 22 includes a U-shaped notch 36 and an elongated opening 32, each of which aligns with mating components on an automobile frame, or alternatively permits venting of the sleeve 20. At the opposite end 28, the carrier 22 defines an opening (not shown), which also aligns with mating components of an automobile frame or alternatively permits venting of sleeve 20. The exterior surface of the carrier 22 supports an outwardly extending C-shaped bracket 30 between the end portions 26, 28.

[0019]Internally, the carrier 22 is reinforced by an interior plate 40, as best seen in FIG. 3. The plate 40 is located approximately at the center portion of the carrier 22, and includes two openings 42, 44 for per...

Abstract

A method of reinforcing an automobile structure includes: providing an elongated hollow automotive frame structure; providing an elongated carrier having a longitudinal axis; applying a reinforcing medium to the carrier for forming a sleeve wherein the reinforcing medium is a heat activated expandable material; and inserting the sleeve in the hollow frame structure.

Description

[0001]This application is a continuation of application Ser. No. 10 / 216,944 filed on Aug. 12, 2002, now U.S. Pat. No. 6,641,208, which is a continuation of application Ser. No. 09 / 524,961 filed on Mar. 14,2000, now U.S. Pat. No. 6,482,486, and claims the benefit of the filing date of both applications.FIELD OF THE INVENTION[0002]This invention relates to a reinforced sleeve coupled to a frame assembly so as to increase the structural strength and stiffness of the frame at selected locations. More particularly, the invention relates to a sleeve coupled to the pillar portion of an automobile frame, wherein the sleeve supports a reinforcing medium that becomes chemically active and expands in response to a predetermined change in ambient conditions.BACKGROUND OF THE INVENTION[0003]For many years the automobile industry has been concerned with designing improved vehicle body structures that absorb or deflect impact loads imposed on the vehicle at or near the passenger compartment. While...
